Gerbera plant named ‘Florush’

ABSTRACT

A new and distinct cultivar of  Gerbera  plant named ‘Florush’, characterized by its compact, upright and uniformly mounding plant habit; freely flowering habit; semi-double type inflorescences with ray florets that are red purple in color; and upright, strong and relatively short scapes.

Botanical designation: Gerbera jamesonii.

Cultivar denomination: ‘Florush’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gerbera plant, botanically known as Gerbera jamesonii and hereinafter referred to by the name ‘Florush’.

The new Gerbera plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new compact container Gerbera cultivars with numerous inflorescences, good garden performance and attractive ray and disc floret coloration.

The new Gerbera plant originated from a cross-pollination in March, 2003 in De Kwakel, The Netherlands of Gerbera jamesonii ‘Fabio’, not patented, as the female, or seed, parent with Gerbera jamesibii ‘Sirene’, not patented, as the male, or pollen, parent. The new Gerbera was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands during the spring of 2004.

Asexual reproduction of the new Gerbera plant by tissue culture in a controlled environment in De Kwakel, The Netherlands since the summer of 2004 has shown that the unique features of this new Gerbera plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Gerbera have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Florush’. These characteristics in combination distinguish ‘Florush’ as a new and distinct cultivar of Gerbera:

-   -   1. Compact, upright and uniformly mounding plant habit.     -   2. Freely flowering habit.     -   3. Semi-double type inflorescences with ray florets that are red         purple in color.     -   4. Upright, strong and relatively short scapes.

Plants of the new Gerbera differ from plants of the female parent, ‘Fabio’, in the following characteristics:

-   -   1. Plants of the new Gerbera are more compact than plants of         ‘Fabio’.     -   2. Plants of the new Gerbera have shorter scapes than plants of         ‘Fabio’.     -   3. Ray florets of plants of the new Gerbera are red purple in         color whereas ray florets of plants of ‘Fabio’ are yellow and         orange in color.

Plants of the new Gerbera differ from plants of the male parent, ‘Sirene’, in the following characteristics:

-   -   1. Plants of the new Gerbera are more compact than plants of         ‘Sirene’.     -   2. Plants of the new Gerbera have shorter scapes than plants of         ‘Sirene’.     -   3. Ray florets of plants of the new Gerbera are red purple in         color whereas ray florets of plants of ‘Sirene’ are pink in         color.

Plants of the new Gerbera can be compared to plants of the Gerbera jamesonii ‘Everlast Carmine’, not patented. Plants of the new Gerbera differ from plants of ‘Everlast Carmine’ in the following characteristics:

-   -   1. Plants of the new Gerbera are more uniform in growth habit         than plants of ‘Everlast Carmine’.     -   2. Plants of the new Gerbera have larger inflorescences than         plants of ‘Everlast Carmine’.     -   3. Plants of the new Gerbera have semi-double type         inflorescences whereas plants of ‘Everlast Carmine’ have single         type inflorescences.     -   4. Ray florets of plants of the new Gerbera are red purple in         color whereas ray florets of plants of ‘Everlast Carmine’ are         dark red in color.     -   5. Plants of the newGerbera have thicker scapes than plants of         ‘Everlast Carmine’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in a glass-covered greenhouse during the winter in De Kwakel, The Netherlands and under conditions and practices which approximate those generally used in commercial container Gerbera production. During the production of the plants, day temperatures ranged from 19° C. to 26° C. and night temperatures ranged from 16° C. to 18° C. Rooted young tissue-cultured plants were planted in 19-cm containers and had been growing for six months when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, 2007, except where general terms of ordinary dictionary significance are used.
